COMPOSITION OF-MATTER FOR TRANSFER PRINTING PROCESSES.

Specification of Letters Patent.

Patented April 20, 1909;

Application filed December 29, 1908. Serial No. 469,846.

To all whom it may concern:

Be it known that I, EMANUEL PIGNONE, a subject of the Kingdom of Italy, and a resident of the borough of Manhattan, city, county, and State of New York, have invented a new and useful Composition of Matter for Use in Transfer Printing Processes.

My invention is applicable to various uses in the arts, but is intended by me to be em ployed more particularly in connection with the decorative arts, in which a design is produced by any suitable means, as, for instance, by perforated sheets of paper or by blocks or type in a suitable printing press, in conjunction with ink or paint so called upon a suitable sheet, such as a iece of bond paper or equivalent materiaf: which sheet is delivered to the consumer to be used by him in transferring the pattern produced thereon by any desired means upon any desired material by laying the same face down upon the material and ressing a hot iron over the reverse side. n this way the composition of matter de osited on the sheet will be partially or w olly melted by the heat and the design transferred, which design is usually thereafter completed on' the material to which it is transferred by needlework, painting, burning, or in any other preferred manner.

Heretofore various com ositions of matter have been em loyed as t e paint or ink, as it is variously ca ed, by the use of which the desired design is produced. Various objections, however, attend the use of such compounds heretofore known, which it is the purpose of my present invention to obviate, and this improvement I accomplish in a very efficient and satisfactory manner, that is to say: 1 I

First: By the employment of my improved paint or ink about to be described, the design may be readily removed from the fabric or other material to which it has been transferred, by the use of cold water and ordinary soap, and does not require the use of chemicals for its removal as some previously used materials do, nor heat nor boiling, in water, for a greater or less time, to accomplish its removal.

Second: My com osition when used as an ink in a press for t e purpose of producing the transfer papers or blocks, does not reuire heat nor moisture in the operation, on t e contrary is used in an entirely cold and ordinary condition.

Third: The composition may be colored with any referred coloring matter in a great variety of colors and in very delicate shades of those colors, if desired.

The composition is as follows: zinc White in oil, about 80 grams; royal baking owder, about 15 grams antimony trisulfid, a out 20 grams; ceiling varnish, about 20 grams; rosin about 20 grams; turpentine, sufficient to reduce the rosin to fluidity.

In order that the ingredients,-royal' baking powder and ceiling varnish above referred to may be better understood, I will state that I use these terms because the materials indicated thereby are well known articles of commerce, to be found practically everywhere in the open market, and the reason I employ the ingredients respectively, is as follows: Royal baking powder is composed of cream of tartar, tartaric acid and bicarbonate of soda, usually having also a percentage of corn starch, and I prefer to use this commercial roduct because it is well known, obtainab e everywhere and the ingredients composing it are of good quality and suitably prepared for the purposes of my invention. However the ingredients which are useful in my product are cream of tartar in combination with the bicarbonate of soda or tartaric acid in combinationwith bicarbonate of soda, but all three ingredients are e 'ually useful because the beneficial results owing from the use of these ingredients is obtained by bringing the bicarbonate of soda in contact with what I call active tartaric acid and both tartaric-acid and cream of tartar are active for the purposes of my invention. The purpose of using these ingredients is that being present in my product in conjunction with antimony trisulfid, as soon as heat is applied for the purpose of effecting the transfer, a slight eifervescing action takes place which disintegrates the crust or glazed surface of the pattern or design, thus softening the same which aids in the more complete and satisfactory transfer of the pattern to the goods. So also the ceiling varnish consists in dissolving two and onehalf parts of rosin in a suitable amount of commercial coal tar naphtha, both of which ingredients in the commercial ceiling varnish are usually of good quality and suitably prepared for my purpose. I desire rosin in my composition and specify it as one of my ingredients and therefore the rosin contained in the ceiling varnish merely carries into my A from to a greater or less degree and yet good results be obtained. For instance, the uantity of ceiling varnish to be used wi depend upon the particular use to which the composltion is to be ut. If used for printing the desi n by and 'over perforated sheets, it shou d be thinner, if used on a printing press, it should be thicker. Therefore the proportions given can, as stated above, be somewhat departed from and yet the essentials of the invention be retained. Also the amount of turpentine used to dissolve the rosin will depend upon the particular degree of fluidity required for any special purpose.

' Having described my invention, I claim:

1. As a new composition of matter a compound composed of zinc white, antimony trisulfid, baking powder comprising starch, tartaric acid and sodium bicarbonate, varnish, rosin, and turpentine in substantially the proportions specified.

2. As a new composition of matter a compound containing zinc white, bicarbonate of soda, tartaric acid, antimony trisulfid, coal tar naphtha, rosin and turpentine in substantia ly the proportions specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EMANUEL PIGNONE.
